Description of problem: I'm getting the following errors while trying to link against boost_regex.so and boost_regex-mt.so (was rebuilding a fedora package called referencer); i guess boost needs to be rebuilt against newer icu. ... configure:3533: checking for main in -lboost_regex-mt configure:3562: g++ -o conftest -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic conftest.cpp -lboost_regex-mt >&5 /usr/lib/gcc/x86_64-redhat-linux/4.1.2/../../../../lib64/libboost_regex-mt.so: undefined reference to `u_isblank_3_7' /usr/lib/gcc/x86_64-redhat-linux/4.1.2/../../../../lib64/libboost_regex-mt.so: undefined reference to `u_digit_3_7' /usr/lib/gcc/x86_64-redhat-linux/4.1.2/../../../../lib64/libboost_regex-mt.so: undefined reference to `u_isspace_3_7' /usr/lib/gcc/x86_64-redhat-linux/4.1.2/../../../../lib64/libboost_regex-mt.so: undefined reference to `u_charType_3_7' /usr/lib/gcc/x86_64-redhat-linux/4.1.2/../../../../lib64/libboost_regex-mt.so: undefined reference to `u_charFromName_3_7' /usr/lib/gcc/x86_64-redhat-linux/4.1.2/../../../../lib64/libboost_regex-mt.so: undefined reference to `u_tolower_3_7' collect2: ld returned 1 exit status ... configure:3468: checking for main in -lboost_regex configure:3497: g++ -o conftest -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic conftest.cpp -lboost_regex >&5 /usr/lib/gcc/x86_64-redhat-linux/4.1.2/../../../../lib64/libboost_regex.so: undefined reference to `u_isblank_3_7' /usr/lib/gcc/x86_64-redhat-linux/4.1.2/../../../../lib64/libboost_regex.so: undefined reference to `u_digit_3_7' /usr/lib/gcc/x86_64-redhat-linux/4.1.2/../../../../lib64/libboost_regex.so: undefined reference to `u_isspace_3_7' /usr/lib/gcc/x86_64-redhat-linux/4.1.2/../../../../lib64/libboost_regex.so: undefined reference to `u_charType_3_7' /usr/lib/gcc/x86_64-redhat-linux/4.1.2/../../../../lib64/libboost_regex.so: undefined reference to `u_charFromName_3_7' /usr/lib/gcc/x86_64-redhat-linux/4.1.2/../../../../lib64/libboost_regex.so: undefined reference to `u_tolower_3_7' Version-Release number of selected component (if applicable): How reproducible: always Steps to Reproduce: 1. 2. 3.

Ping !! A bug fix for referencer is being held because of this. Thanks.
I have the same error trying to update source-highlight.
I had the same problem when compiling the lyx source. I found two interesting facts :-) First a bug in boost where boost_regex uses ICU library without linking to it. http://svn.boost.org/trac/boost/ticket/1083 From there I notice that u_digit_3_7 is strangely closed to the version of libicu that is installed: libicu-3.8-0.2.d02.fc8 $ grep u_digit /usr/include/unicode/* /usr/include/unicode/uchar.h: * This is equivalent to u_digit(c, 16)>=0. /usr/include/unicode/uchar.h:u_digit(UChar32 ch, int8_t radix); /usr/include/unicode/uchar.h: * @see u_digit /usr/include/unicode/urename.h:#define u_digit u_digit_3_8 So it seems that boost needs to be rebuilt with the latest libicu.
(In reply to comment #3) > > First a bug in boost where boost_regex uses ICU library without linking to it. > http://svn.boost.org/trac/boost/ticket/1083 In case it was not clear I am not implying that F-8 (to be) has this problem but only that this lead me to the find what was the problem. Rebuilding the source rpm fixed the problem.
I'm rebuilding this now. Thanks for the heads up.
I was able to rebuild referencer successfully with the re-built boost. it'll be great though if the root cause (as noted in comment #3) could be fixed.
